Great movie from 2020. Until now Collodion: The Process of Preservation is the best online movie I've seen this year. The movies industry, can't really boast with a large number of better Documentary films. Collodion: The Process of Preservation is definitely one of these movies that you can watch several times and always find something new, and something interesting. The soundtrack is the greatest asset of this film. I hope you're excited, so start watching it now!.
